passing dictionaries through COM

or leave it in the dictionary, add amethod to return the keys,  and add a
method that lets you get at what you need. i.e.

def get_keys():
    return self.mydict.keys()

def get_value(key):
    return self.mydict[key]

this always seems easier to me, and seems to use more python and less VB.
one caveat -- if you run code like this inside the VB IDE updating values
can fail.  this is due to how VB deals with late bound objects, which is to
say not very well.
